Invoicing error - only with CIL activated

When we invoice a sales order we get an error with the text shown below. If I remove the CIL-checkmark in the user options it runs successfully. 

I have traced the error to the method initInvoiceHeaderFromSourceTable on the class SalesInvoiceJournalCreate that calls the method initFromSalesTable on the table CustInvoiceJour. 

When running with the CIL checkmark set true the method initFromSalesTable exits successfully however it does not continue the execution in the method initInvoiceHeaderFromSourceTable. Instead it throws the below error message.

The main result is that we cannot post an invoice on the customers installation without removing the CIL checkmark.

Thanks in advance,
